Construction Engineering and Management (CEM) is a broad domain with publications covering interrelated subdisciplines and considered a key source of knowledge sharing. Previous studies used scientometric methods to assess the current impact of CEM publications; however, there is a need to predict future citations of CEM publications to identify the expected high-impact trends in the future and guide new research efforts. To tackle this gap in the literature, the authors conducted a study using Machine Learning (ML) algorithms and Social Network Analysis (SNA) to predict CEM-related citation metrics. Using a dataset of 93,868 publications, the authors trained and tested two …

Phases And Dynamics Of Few Fermionic Impurities Immersed In Two-Dimensional Boson Droplets, Jose Carlos Pelayo, Thomás Fogarty, Thomas Busch, Simeon I. Mistakidis

Physics Faculty Research & Creative Works

We unravel the ground state properties and emergent nonequilibrium dynamics of a mixture consisting of a few spin-polarized fermions embedded in a two-dimensional bosonic quantum droplet. For an increasingly attractive droplet-fermion interaction we find a transition from a spatially delocalized fermion configuration to a state where the fermions are highly localized and isolated. This process is accompanied by the rise of induced fermion-fermion interactions mediated by the droplet. Additionally, for increasing attractive droplet-fermion coupling, undulations in the droplet density occur in the vicinity of the fermions manifesting the back-action of the latter. Following interaction quenches from strong to weaker attractive …

Efemp1 Haploinsufficiency Causes A Marfan-Like Hereditary Connective Tissue Disorder, Irman Forghani, Steven H Lang, Matthew J Rodier, Stephanie A Bivona, Alejo A Morales, Stephan Zuchner, Guney Bademci, Mustafa Tekin

Faculty, Staff and Students Publications

Phenotypic features of a hereditary connective tissue disorder, including craniofacial characteristics, hyperextensible skin, joint laxity, kyphoscoliosis, arachnodactyly, inguinal hernia, and diverticulosis associated with biallelic pathogenic variants in EFEMP1 have been previously described in four patients. Genome sequencing on a proband and her mother with comparable phenotypic features revealed that both patients were heterozygous for a stop-gain variant c.1084C>T (p.Arg362*). Complementary RNA-seq on fibroblasts revealed significantly reduced levels of mutant EFEMP1 transcript. Considering the absence of other molecular explanations, we extrapolated that EFEMP1 could be the cause of the patient's phenotypes. Furthermore, nonsense-mediated decay was demonstrated for the mutant allele …

Cadherin-11 Targeted Cell-Specific Liposomes Enabled Skin Fibrosis Treatment By Inducing Apoptosis, Himanshu N Bhatt, Rimpy Diwan, Igor L Estevao, Rui Dong, Jennifer Smith, Chuan Xiao, Sandeep K Agarwal, Md Nurunnabi

Faculty, Staff and Students Publications

Continuous and aberrant activation of myofibroblasts is the hallmark of pathological fibrosis (e.g., abnormal wound healing). The deposition of excessive extracellular matrix (ECM) components alters or increases the stiffness of tissue and primarily accounts for multiple organ dysfunctions. Among various proteins, Cadherin-11 (CDH11) has been reported to be overexpressed on myofibroblasts in fibrotic tissues. Anti-apoptotic proteins such as (B cell lymphoma-2) (BCL-2) are also upregulated on myofibroblasts. Therefore, we hypothesize that CDH11 could be a targeted domain for cell-specific drug delivery and targeted inhibition of BCL-2 to ameliorate the development of fibrosis in the skin. To prove our hypothesis, we …

Myocardial Infarction Suppresses Protein Synthesis And Causes Decoupling Of Transcription And Translation, Shijie Liu, Vaibhav Deshmukh, Fangfei Wang, Jie Liang, Jenna Cusick, Xiao Li, James F Martin

Faculty, Staff and Students Publications

Gene expression involves transcription, translation, and mRNA and protein degradation. Advanced RNA sequencing measures mRNA levels for cell state assessment, but mRNA level does not fully reflect protein level. Identifying heart cell proteomes and their stress response is crucial. Using a cardiomyocyte-specific mouse model, we tracked protein synthesis after myocardial infarction. Our results showed that myocardial infarction suppresses protein synthesis and unveils a decoupling of translation and transcription regulation in cardiomyocytes.

Faculty, Staff and Students Publications

Trypanosoma cruzi is the causative agent of Chagas disease, a global public health problem. New therapeutic drugs and biologics are needed. The TSA-1 recombinant protein of T. cruzi is one such promising antigen for developing a therapeutic vaccine. However, it is overexpressed in E. coli as inclusion bodies, requiring an additional refolding step. As an alternative, in this study, we propose the endogenous cysteine protease inhibitor chagasin as a molecular scaffold to generate chimeric proteins. These proteins will contain combinations of two of the five conserved epitopes (E1 to E5) of TSA-1 in the L4 and L6 chagasin loops. Twenty …

The Myth Of Slavery Abolition, Jocelyn Getgen Kestenbaum

Articles

In many countries today, slavery and the slave trade continue with impunity. International human rights law prohibits both abuses, but states are rarely held accountable and people who are enslaved or slave traded rarely receive redress. This Article offers a novel account of why international human rights law advocacy neglects slavery and the slave trade. Specifically, this Article demonstrates that the abolition of the Transatlantic and East African slave trades was achieved through a legal framework that marginalized the human rights of enslaved persons while consolidating empire. In the wake of World War II, prohibitions on slavery and the slave …

Spanish Heritage Speakers’ Processing Of Lexical Stress, Ramsés Ortín

Writing and Language Studies Faculty Publications

This study examines the status of lexical stress in the processing system of heritage speakers of Spanish and whether or not it is influenced by their experience with English. Participants completed an ABX matching task with auditory stimuli differing in the location of stress or in one consonantal sound. Findings reveal that heritage speakers are more accurate in consonant-based trials than in stress-based ones, but only when matching stimuli were non-adjacent, which suggests that their stress-processing strategies pattern more closely with those of native English speakers. Furthermore, dominance and knowledge of Spanish appear to be associated with increased phonological sensibility …
